Performance-Monitoring Counters Library, for Intel/AMD Processors and Linux
This example introduces
   rabbit command-line options --Enable m,n --PC m,n --APIC m,n

Return to Main Menu


Command-Line Options --Enable m,n Pentium Pro/II/III and Athlon only. Set m = 0 to disable both performance counters (Intel) or all four performance counters (Athlon). --PC m,n Exert control over the processor's PM0 and PM1 output pins (PC = Pin Control). They can be configured to signal each time the counter increments, or to signal on overflow. Probably, no one is watching. At one time, Intel built a special socket that paid attention, and rerouted the signals. --APIC m,n Pentium Pro/II/III and Athlon only. Exert control over the processor's local Advanced Programmable Interrupt Controller. Requires a patched version of Linux.
Notes Avoid these options.
